How do i show my working when trying to work out 3 1/3 divided by 4?

Answer:

5/6

Step-by-step explanation:

When dividing fractions, we use a rule where we keep the first number, change the sign, and flip the second number.

3 1/3 must be converted to an improper fraction before we can do this, though.

3 1/3 is 10/3 because we multiply 3 by the denominator, also 3, and then add one, so 10/3.

Now we can divide. Remember 4 is the same thing as 4/1

10/3 ÷ 4/1

Keep the first fraction the same, change the division sign into a multiplication sign, and divide by flip the second fraction.

It ends up looking like 10/3 x 1/4

Multiply: 10 x 1 and 3 x 4

It's 10/12, but we can simplify that by dividing both the top and the bottom by 2.

The final answer is 5/6

eimsori [14]

Answer:225000 mice

Step-by-step explanation:

Mass of elephant=4500kg

Mass of mice=2x10^(-2)=2/100 kg

Let y be there number of mice

2/100 x y=4500

2y/100=4500

Cross multiply

2y=4500 x 100

2y=450000

Divide both sides by 2

2y/2=450000/2

y=225000

Answer:

9 white ribbons were awarded

Step-by-step explanation:

make white x

make blue b and make red r

b=x-1

r=x+3

w=x

add them up

x-1+x+3+x=29

x-1 +x+3 is 2x+2

2x+2+x=29

3x+2=29

subtract 2 on both sides

3x=27

divide by 2

x=9

How can you get equation b from equation A. 3(x+2)=18 B. X+2=18
Rzqust [24]

Answer:

We start with the equation:

A: 3*(x + 2) = 18

And we want to construct equation B:

B: X + 2 = 18

where I suppose that X is different than x.

Because in both equations the right side is the same thing, then the left side also should be the same thing, this means that:

3*(x + 2) = X + 2

Now we can isolate the variable x.

(x + 2) = (X + 2)/3

x = (X + 2)/3 - 2

Then we need to replace x by  (X + 2)/3 - 2 in equation A, and we will get equation B.

Let's do it:

A: 3*(x + 2) = 18

Now we can replace x by =  (X + 2)/3 - 2

3*( (X + 2)/3 - 2 + 2) = 18

3*(  (X + 2)/3 ) = 18

3*(X + 2)/3 = 18

(X + 2) = 18

Which is equation B.
